Ovens
Curing Ovens for Surface Coating Requirements
Intech stands at the forefront as a leading manufacturer of ovens, showcasing excellence in design and functionality. Our Paint Baking Ovens are specially designed for surface coating requirements, build for continuous operation delivering top-notch quality used for powder coating, varnish drying, PVC drying and paint curing. Intech manufactures three types of curing ovens Ground mounted, Camel back and Diamond loop.
Ovens play a crucial role in baking powder/paint layers onto article surfaces. Convection heating, using either electrical, HSD, LPG, IR heaters, or a thermic fluid system, circulates hot air over the articles for curing. Blowers draw cooled air over heat exchangers or electrical heaters and direct the heated air into the oven through air-directional blinds, making these ovens versatile for both conveyorized and batch operations.

Types of Ovens
Ground Mounted Oven
Camel Back Oven
Diamond Loop Oven
Diamond loop ovens use a looping configuration to enhance heat transfer efficiency and ensure uniform curing and baking.. This innovative design promotes consistent airflow, making these ovens highly effective for precision in industrial applications. Diamond loop ovens stand out for their reliability and capability to deliver superior results across various materials.
Frequently Asked Questions (FAQs)
What are the three main types of powder curing ovens offered by Intech?
Intech specializes in three distinct overhead conveyor oven designs:
Ground Mounted Oven: A traditional, straight-line oven installed at ground level.
Camel Back Oven: Features a raised horizontal section (the “hump”) in the middle of the oven.
Diamond Loop Oven®: A compact, vertical-style oven where the conveyor path forms a diamond shape, maximizing curing length in a small footprint.
Why should I choose an Intech oven over other brands?
Intech is known for its expertise in thermal processing and energy efficiency. Key advantages include:
Proven Designs: Each oven type is engineered to solve specific production challenges.
Superior Airflow & Temperature Uniformity: Patented airflow systems ensure consistent cure quality.
Energy Efficiency: Advanced insulation and recirculation technology reduce operating costs.
Durability: Built with robust materials for long life in an industrial environment.
What is the best application for a Ground Mounted Oven?
The Ground Mounted Oven is ideal for:
Standard Production Lines: Where floor space is readily available and a straight-line process flow is desired.
Heavy or Large Parts: Its straightforward design provides excellent stability for curing large, massive items.
Simplicity and Cost-
Effectiveness: Often the most economical choice for basic curing requirements.
What is the primary function of Powder Curing Oven?
The primary function is to heat powder-coated parts to a specific temperature for a precise amount of time (cure schedule). This process melts the powder, allows it to flow and then triggers a chemical cross-linking reaction, creating a durable, high-quality finish.
What are the key benefits of the Camel Back Oven design?
The Camel Back Oven offers several unique advantages:
Natural Drip-Off Area: The elevated center section creates a pre-heat zone. As parts enter and begin to heat, any potential “powder sag” or drips occur before the part reaches the highest temperature, minimizing finish defects.
Improved Temperature Profiling: The design allows for better zoning and heat control.
Space Efficiency (Vertical): It utilizes vertical space, requiring less floor length than an equivalent-capacity straight oven.
When should I consider a Diamond Loop Oven?
The Diamond Loop Oven is the perfect solution when:
Floor Space is Extremely Limited: It provides the longest cure time in the smallest possible footprint.
You Need a High-Production Rate in a Compact Area: Its continuous loop design is highly efficient.
You Want to Maximize Energy Efficiency: The design minimizes heat loss to the surrounding plant
How do I decide which oven type is right for my plant?
The choice depends on several factors:
Available Floor Space & Ceiling Height: Diamond Loop for tight spaces, Camel Back for moderate space, Ground Mounted for ample space.
Part Characteristics: Long, flexible parts may be better suited for a straight-line oven, while most standard parts work well in all types.
Production Volume and Required Cure Time: Diamond Loops offer long cure times in a small area.
Budget: Ground Mounted ovens are typically the most budget-friendly initial investment.
What heating systems are available?
Intech ovens can be configured with various energy sources, including:
Direct Gas Fired (DGF): Most common and efficient, introducing hot combustion air directly into the oven.
Indirect Gas Fired (IGF): Uses a heat exchanger; essential if combustion fumes cannot contact the parts.
Electric: Clean and precise, often used for smaller ovens or where gas is not available.
How is the oven integrated with our existing overhead conveyor?
Intech designs the oven to be a seamless part of your production line. The oven will include precisely aligned inlet and outlet vestibules with entry/exit seals to contain heat. The conveyor track runs continuously through the oven.
Does Intech provide installation and training services?
Yes. Intech typically offers comprehensive support, including installation supervision, commissioning, and thorough operator and maintenance training to ensure your team can run the oven safely and efficiently.
Do Intech ovens meet relevant safety standards?
Yes, Intech ovens are designed and built to comply with applicable industrial safety standards, such as those from NFPA (National Fire Protection Association) and OSHA. Specific certifications can be discussed during the design phase.
Can the oven be modified or expanded in the future?
While ovens are custom-built for initial requirements, Intech can often provide modification services in the future. It’s best to discuss potential future needs during the initial design phase to allow for easier expansion.
